“…The most popular methods are Phase Shifted Pulse Width Modulation (PSPWM) and level-shifted PWM [21,22]. PSPWM method is the most suitable PWM and is recommended for cascaded H-Bridge converters [23] and is extensively used for its ease of implementation and even power distribution amongst the cells.…”

Abstract-Cascaded H-Bridge converter has recently been utilized in different high-power applications due to its modular and simple structure. In order to have a balanced operation after a fault occurrence in this converter, it is necessary to detect the switch fault and its location. In this paper, a fast power switch fault detection method is presented to identify the fault and its location. Only one voltage measurement per phase is required by this method, and the fault detection is faster compared to the existing methods. Moreover, it is suitable for implementation on an FPGA device, due to the use of simple math, relational and state machine blocks. The proposed method is verified by computer simulations and FPGA-based experimental tests.

Digital signal processor (DSP) and field programmable gate array (FPGA) based concentrated control systems are designed for implementing CPS-SPWM strategies. The self-defined universal asynchronous receiver/transmitter (UART) protocol is used for communication between a master controller and an individual module controller via high speed links. Aimed at undesired pulse competition, this paper analyzes its generation mechanism and presents a new method for eliminating competition pulses with no time delay. Finally, the proposed concentrated controller is applied to a 10kV/10MVar distribution static synchronous compensator (DSTATCOM) industrial prototype. Experimental results show the accuracy and reliability of the concentrated controller, and verify the superiority of the proposed elimination method for competition pulses.

“…Industrial topologies have been presented [12]. Different pulse-width modulation techniques for symmetrical cascade inverters with high and fundamental switching frequency have been shown, for instance, in [13,14]. An improvement in terms of efficiency of the converter is presented in [15] where the authors use different DC sources to reduce the switching losses.…”

The paper presents a novel technique to control the current of an electromagnetic linear actuator fed by a multilevel IGBT voltage inverter with dynamic energy storage. The technique uses a "cascade model predictive control (MPC), " which consists of two MPCs. A predictive control of the trajectory position predicts the optimal current, which is considered to be the desired current for the second MPC controller in which a hysteresis control technique is also integrated. Energy is stored in a capacitor using energy recovery. The current MPC can handle a capacitor voltage higher than the source voltage to guarantee high dynamic current and disturbance compensation. The main contribution of this paper is the design of an optimal control structure that guarantees a capacitor recharge. In this context, the approach is quite new and can represent a general emerging approach allowing to reduce the complexity of the new generation of inverters and, in the meantime, to guarantee precision and acceptable switching frequency. The proposed technique shows very promising results through simulations with real actuator data in an innovative transportation technology.
